Default OIL IN THE WATER - mercruiser 6 cyliner 165 hp

Thanks for your reply. The boat was docked during the storm and the
stern was into the wind and waves. the water rose almost 4 feet at the
dock. my dock is at the dead end of a logoon.
i checked the boat many times to see that the pump was keeping up with
the rain water.
i did not think the water could be pushed up into the engine.



Unfortunately it can, particularly if there are heavy waves breaking against
the stern. There are exhaust "flappers" that act like check valves that are
supposed to prevent this from happening under normal conditions, but often
they are frozen open or simply rotted away. With 900 hours on the engine,
that is a distinct possibility.

The danger of trying to start the engine right now is that one or more of
the cylinders may have water in them.
Starting the engine could cause a hydrolocked condition, causing serious
engine damage. (water does not compress).

I think your engine is salvagable assuming no damage has been done other
than getting water in the oil.
I'll defer to the engine experts to give you the best advice as to how to
proceed from here.



if this is the case then some engine cranking with the plugs out and
another oil change might save the engine ?


Yes. And perhaps even another oil and filter change after that.



do you all think the motor is salvageable ???


Yes.
Sorry for your problems, but I think it can be fixed.
